We performed thoracoscopic thymectomy using a method in which the anterior chest wall was lifted by Kirschner wire passed through the subcutaneous tissue. Between April 2011 and May 2012, 5 cases underwent thoracoscopic thymectomy using this method. Postoperative complications, especially subcutaneous hematoma and pain in the anterior chest wall through which the Kirschner wire was passed, did not occur. This method provided a good operative field in the posterior sternum for safe thymectomy. In addition, the use of an Endocameleon was effective decreasing invisible field blind view during the operation. We concluded that this method is a simple and useful means of elevation of the sternum for thoracoscopic thymectomy.
